libctf, ld: CTF dumper changes for consistency

Browse Source 
In most places in CTF dumper output, we emit 0x... for hex strings, but
in three places (top-level type IDs, string table offsets, and the file
magic number) we don't emit the 0x.

This is very confusing if by chance there are no hex digits in the
output.  Add 0x consistently to everything, and adjust tests
accordingly.  While we're at it, improve the indentation of the output
so that subsequent lines in aggregate output are indented by at least as
many columns as the colon in the type output.  (Subsequent indentation
is still 4 spaces at a time.)

libctf/ChangeLog
2021-01-05  Nick Alcock  <nick.alcock@oracle.com>

	* ctf-dump.c (ctf_dump_format_type): Add 0x to hex type IDs.
	(ctf_dump_header): Add 0x to the hex magic number.
	(ctf_dump_str): Add 0x to the hex string offsets.
	(ctf_dump_membstate_t) <cdm_toplevel_indent>: New.
	(ctf_dump_type): Adjust.  Free it when we're done.
	(type_hex_digits): New.
	(ctf_dump_member): Align output depending on the width of the type
	ID being generated.  Use printf padding, not a loop, to generate
	indentation.
